Total trash! Don't buy
Didn't even make it 12 months before it went out again. So once again I have to crawl under the dash of my car to disconnect this piece of garbage and replace it. It started leaking out the bottom of it. The car is un-drivable.

Not the correct match
The orientation to the firewall is horizontal and the hose size is smaller. The hose is size 10,should be size 12 and it's accessible to the top not the side. The vehicle is D-max 2009 model, 300cc

Failed after a little over a year and a half
I used this in a 2011 WRX and it failed after a little after a year and a half. Parts of this product feel cheap. I would not recommend this product especially with all the time it takes to install and bleed.
